Description

Technical Field

[0001] The present invention relates to the technical field of medical device detection, and in particular to a drug bottle defect detection device and a detection method. Background Art

[0002] Pharmaceutical bottles are usually containers made of glass or plastic for storing medicines. Their production has strict requirements and standards. Among them, pharmaceutical bottle defect detection is an important part of quality control in the pharmaceutical industry, and its purpose is to ensure the safety and effectiveness of medicines. Pharmaceutical bottle defect detection involves many types, including cracks, breakage, foreign matter, stains, label defects, size deviation, bubbles, uneven color, etc.

[0003] For example, a Chinese patent with publication number CN112129783A discloses a transparent medicine bottle bottom defect detection device based on deep learning, including an industrial computer, a precision adjustment mechanism, a precision limit mechanism, a medicine bottle clamping mechanism, an image acquisition device, an image processing and detection system, an industrial camera precision adjustment platform and an imaging mechanism. The detection method includes acquiring a color image; using histogram equalization, Laplace operator, logarithmic Log transform, gamma transform and other image enhancements; finding the target edge contour of the grayscale image and locating the boundary; obtaining the affine transformation matrix through the angle and correcting the image; determining the position of the target in the image and making a positioning point; using a rectangular frame to select the target area and cut out the target; obtaining the final data rinsed image; importing the rinsed image into the medicine bottle image deep learning detection algorithm, obtaining two probability values ​​of the qualified medicine bottle probability value and the defective medicine bottle probability value and normalizing them, comparing the two probability values, and obtaining the probability value of the optimal decision.

[0004] However, the above-mentioned medicine bottle bottom defect detection device still has some shortcomings in actual use:

[0005] 1. First, in the prior art, the bottle body is photographed by an image acquisition device, and then the defects of the bottle body are detected with an industrial computer. However, it should be noted that the image acquisition device directly photographs the entire bottle body, which will cause the image of the bottle body to be relatively concentrated in the entire image. At this time, when the image is magnified for detection, large and small pixels will appear in the image, affecting the detection of the bottle body, making it impossible to effectively identify some tiny scratches on the bottle body. Therefore, the effect of first photographing the bottle body and then magnifying it for detection is significantly different from that of directly magnifying and shooting.

[0006] 2. The prior art has a certain degree of singularity, and is only capable of performing defect detection on drug bottles of a single size, but is unable to perform defect detection on drug bottles of different sizes, thus affecting the applicability of the equipment.

[0042] The following is combined with Figure 1-Figure 10 This application is described in further detail.

[0043] The embodiment of the present application discloses a drug bottle defect detection device and a detection method; it is explained that the drug bottle A defect detection device is mainly used in the process of batch quality inspection of drug bottles A.

[0044] In the prior art, the bottle body is photographed by an image acquisition device, and then the defects of the bottle body are detected in conjunction with an industrial computer. However, it should be noted that the image acquisition device directly photographs the entire bottle body for detection, which will result in a relatively concentrated image of the bottle body in the entire image. At this time, when the image is magnified for detection, large and small pixels will appear in the image, affecting the detection of the bottle body, and making it impossible to effectively identify some tiny scratches on the bottle body. Therefore, the effect of first photographing the bottle body and then magnifying it for detection is significantly different from that of directly magnifying and photographing it.

[0045] In the prior art, the prior art has a certain degree of singleness, and it can only perform defect detection on a single-sized drug bottle A, and cannot perform defect detection on drug bottles A of different sizes, thereby affecting the applicability of the equipment.

[0046] Therefore, the present application proposes a drug bottle defect detection device.

[0047] See also Figure 1 , which is a schematic diagram of the structure of the entire device in this application; a drug bottle defect detection device, comprising: a stationary detection platform 1. The detection platform 1 is generally set on the ground of the factory to ensure the stability of the entire device.

[0048] The medicine bottle conveyor 2 is symmetrically arranged on the detection platform 1 and is used for conveying the medicine bottle A. The medicine bottle conveyor 2 includes two symmetrically distributed clamping conveyor belts 20, and the clamping conveyor belts 20 are evenly spaced with clamping blocks 21 for clamping the medicine bottle A.

[0049] It should be noted that the clamping block 21 is made of rubber. Not only can the drug bottle A be clamped and limited by the clamping block 21, but also the clamping block 21 is made of rubber, which can protect the surface of the drug bottle A and avoid damage during the detection process.

[0050] The clamping conveyor belt 20 is provided with a plurality of clamping blocks 21 to ensure the automatic and continuous conveying of the medicine bottles A, which can greatly improve the efficiency of the inspection of the medicine bottles A.

[0051] See also Figure 2 and Figure 3 As shown, it is a structural schematic diagram of the conveying of the medicine bottle A in the present application; the medicine bottle conveying member 2 also includes a moving block 22 slidably arranged on the detection platform 1, and a plurality of conveying rollers 23 are rotatably arranged on the moving block 22, and the clamping conveyor belt 20 is symmetrically sleeved on the conveying rollers 23 on the detection platform 1, and the two clamping conveyor belts 20 are symmetrically distributed, and the conveying rollers 23 are connected to a conveying motor 26.

[0052] A bidirectional adjustment rod 24 is screwed between the moving blocks 22 in the width direction of the detection platform 1 , and a synchronous adjustment belt 25 is installed on the bidirectional adjustment rod 24 .

[0053] During the specific implementation process, the conveying motor 26 is started, and the conveying motor 26 drives the clamping conveyor belt 20 to rotate through the conveying roller 23, and then the two clamping conveyor belts 20 rotate synchronously relative to each other. During the rotation of the two clamping conveyor belts 20, the clamping blocks 21 on the two clamping conveyor belts 20 approach each other, and the drug bottle A to be tested can be clamped between the two clamping blocks 21 to achieve the limitation of the drug bottle A, and then the clamping conveyor belt 20 continues to move, which can drive the drug bottle A to move along the length direction of the detection platform 1.

[0054] Furthermore, in order to ensure the applicability of the equipment in the present application, the present application can also clamp and convey medicine bottles A of different sizes; rotate the two-way adjustment rod 24, and the two-way adjustment rod 24 drives the symmetrically distributed moving blocks 22 on the detection platform 1 to move relatively through the synchronous adjustment belt 25; specifically, rotate the two-way adjustment rod 24 clockwise, the symmetrically distributed moving blocks 22 move away from each other, and the moving blocks 22 drive the two symmetrical clamping conveyor belts 20 to move away from each other, and then the larger medicine bottle A can be clamped and conveyed; rotate the two-way adjustment rod 24 counterclockwise, the symmetrically distributed moving blocks 22 move closer to each other, and the moving blocks 22 drive the two symmetrical clamping conveyor belts 20 to move away from each other, and then the smaller medicine bottle A can be clamped and conveyed. Correspondingly, defect detection can also be performed on medicine bottles A of different sizes.

[0055] See also Figure 4 As shown, it is a structural schematic diagram of surface defect detection of the drug bottle A in the present application; a plurality of industrial cameras 4 for defect detection of the drug bottle A are also installed on the detection platform 1, and the industrial cameras 4 are slidably set on the detection platform 1, and the camera end of the industrial camera 4 extends toward the direction of the drug bottle A clamped between the clamping conveyor belts 20.

[0056] After the clamping conveyor belt 20 controls the medicine bottle A to move to the first detection area, the industrial camera 4 in the first detection area starts to work, takes a picture of the medicine bottle A, and then analyzes it in the computer to detect whether there are defects on the surface of the medicine bottle A.

[0057] See also Figure 4 , Figure 5 and Figure 6 As shown, it is a structural diagram of lifting the medicine bottle A; a lifting plate 5 for lifting the medicine bottle A is also arranged between the two clamping conveyor belts 20 on the detection platform 1, and the top of the lifting plate 5 is a stepped structure, and the height of the medicine bottle A is adjusted by the lifting plate 5.

[0058] It should be noted that the lifting plate 5 is a stepped structure, and the position corresponding to each step of the lifting plate 5 is named as the first detection area, the second detection area, the third detection area, and so on.

[0059] After the drug bottle A is inspected for defects in the first inspection area, the clamping conveyor belt 20 continues to move, controlling the drug bottle A to move to the second inspection area, and then the industrial camera 4 in the second inspection area inspects the drug bottle for defects. Then the clamping conveyor belt 20 continues to move, controlling the drug bottle A to be inspected for defects in the third inspection area and the fourth inspection area. If there are no surface defects after the inspection, the drug bottle A will be collected uniformly. If there are defects on the surface of the product after the inspection, it will be rejected.

[0060] During the specific implementation process, the clamping conveyor belt 20 moves, and the bottom of the medicine bottle A located between the two clamping blocks 21 on the clamping conveyor belt 20 abuts against the lifting plate 5 and moves along the upper end surface of the lifting plate 5. When the medicine bottle A moves to the first detection area of ​​the lifting plate 5, the bottle mouth and the bottle bottom of the medicine bottle A are exposed to the outside and can be photographed. The bottle mouth and the bottle bottom of the medicine bottle A can be detected through multiple sets of photos.

[0061] Then the medicine bottle A continues to move, and an upward force is applied to the bottom of the medicine bottle A through the lifting plate 5. At this time, the upper half of the medicine bottle A is exposed in the second detection area, which can be photographed. Multiple sets of photos can be used to detect the part of the medicine bottle A below the bottle mouth and above the middle of the bottle body.

[0062] Then the medicine bottle A continues to move, and an upward force is applied to the bottom of the medicine bottle A through the lifting plate 5. At this time, the middle part of the medicine bottle A is exposed in the third detection area, which can be photographed, and the middle part of the medicine bottle A can be detected through multiple sets of photos.

[0063] Then, the medicine bottle A continues to move, and an upward force is applied to the bottom of the medicine bottle A through the lifting plate 5. At this time, the middle and lower part of the medicine bottle A is exposed in the fourth detection area, which can be photographed, and the middle part of the medicine bottle A can be detected through multiple sets of photos.

[0064] The lifting plate 5 in the present application can lift and lower the medicine bottle A at equal intervals, dividing the entire bottle body of the medicine bottle A into multiple different areas, and then performing a separate inspection on each area. In this way, each area can be enlarged and photographed, which can effectively improve the accuracy of the inspection of each area and avoid directly photographing and inspecting the medicine bottle A, which will cause it to be enlarged during inspection and cause blurred pixels and mosaics.

[0065] Furthermore, in order to detect medicine bottles A of different sizes, the present application also proposes a replacement component 6, by which different areas of medicine bottles A of different lengths can be detected.

[0066] Look again Figure 5 and Figure 6 As shown, one side of the lifting plate 5 is also provided with a replacement component 6 for controlling the replacement of lifting plates 5 of different sizes, the replacement component 6 includes a replacement threaded rod 60 that rotates through a bearing on the detection platform 1, and a number of different replacement blocks 61 are screwed on the replacement threaded rod 60, and vertical columns 62 are installed on the several replacement blocks 61. Lifting plates 5 of different sizes are installed on the several vertical columns 62, and a reset tension spring 63 is provided between the lifting plate 5 and the replacement block 61 and is sleeved on the vertical column 62.

[0067] A return column 64 is installed on one side of the length direction of the plurality of lifting plates 5, and a return plate 65 is installed on the detection platform 1. The return column 64 is slidably set on the return plate 65, and a return groove 66 for the return column 64 to slide is opened on the return plate 65.

[0068] It should be noted that the lifting plates 5 are arranged at equal intervals on the detection platform 1; and the lifting plates 5 are all located at the bottom of the clamping conveyor belt 20; and the return chute 66 on the return plate 65 is a wave crest structure.

[0069] During the specific implementation process, when a larger-sized drug bottle A is inspected, it is necessary to replace the lifting plate 5 with a higher step difference to ensure the lifting and lowering of the drug bottle A. At this time, the threaded rod 60 is rotated to drive the several lifting plates 5 screwed on its upper end to move until the corresponding lifting plate 5 moves to the bottom of the two clamping conveyor belts 20.

[0070] During the movement of the lifting plate 5, the alignment column 64 on the side wall of the lifting plate 5 will control the height of the lifting plate 5. When the required lifting plate 5 moves to the specified position, the lifting plate 5 is located at the top of the wave crest of the alignment slot 66. At this time, the first detection area of ​​the lifting plate 5 is in conflict with the medicine bottle body A, so that defect detection of the medicine bottle body A can be realized.

[0071] In addition, the present application also proposes an angle adjustment component 3, see Figure 7 and Figure 8 As shown, the drug bottle A can be rotated by the adjusting component 3, and the drug bottle A clamped on the two clamping conveyor belts 20 can be intermittently adjusted in angle to ensure multi-angle detection of the surface of the drug bottle A. A plurality of angle adjustment components 3 are arranged at equal intervals on the detection platform 1, and the angle adjustment component 3 includes two telescopic telescopic skeletons 30, and the corners of the two telescopic skeletons 30 are rotatably provided with a limit shaft 31, and the limit shaft 31 on the telescopic skeleton 30 is provided with an angle adjustment belt 32.

[0072] It should be noted that the two telescopic frames 30 are telescopic structures.

[0073] In specific implementation, when the medicine bottle A enters the first inspection area, the industrial camera 4 takes a picture of it, and then analyzes the photographed picture to detect defects on its surface. However, it can only detect one side of the medicine bottle A, and the medicine bottle A is a 360-degree three-dimensional structure. Therefore, the industrial camera 4 cannot capture multiple sides of the medicine bottle A in place. Therefore, the present application proposes an angle adjustment component 3.

[0074] Start the micro motor 33, which drives the limit shaft 31 to rotate, and then the limit shaft 31 drives the angle adjustment belt 32 to rotate. When the medicine bottle A enters the first detection area, the angle adjustment belt 32 will contact the surface of the medicine bottle A to control the rotation of the medicine bottle A. During the rotation process, the industrial camera 4 takes pictures of it multiple times, which can greatly improve the accuracy of defect detection of the medicine bottle A.

[0075] Look again Figure 8 As shown, a tensioning wheel 34 is pressed against one side of the angle adjustment belt 32 , and a tensioning spring 35 is connected to the tensioning wheel 34 through a bracket. The tensioning spring 35 is installed on a right-angle block 38 , and the right-angle block 38 is installed on the detection platform 1 .

[0076] A telescopic adjustment screw 36 is rotatably mounted on one side of the right-angle block 38 via a bearing, and the two telescopic frames 30 are screwed onto the telescopic adjustment screw 36 .

[0077] When testing medicine bottles A of different sizes, the circumferences of medicine bottles A of different sizes are also different. Therefore, in order to ensure that the medicine bottle A can rotate a complete circle, the present application proposes a telescopic adjustment screw 36, which is used to control the length between the two telescopic frames 30.

[0078] When the circumference of the detected medicine bottle A is longer, the telescopic adjustment screw 36 is rotated clockwise, and the two telescopic frames 30 on the telescopic adjustment screw 36 move outward until the length of the two telescopic frames 30 becomes longer, wherein the length of the two telescopic frames 30 is the same as the circumference of the medicine bottle A.

[0079] When the circumference of the detected medicine bottle A is shorter, the telescopic adjustment screw 36 is rotated counterclockwise, and the two telescopic frames 30 on the telescopic adjustment screw 36 move inward until the length of the two telescopic frames 30 becomes shorter, wherein the length of the two telescopic frames 30 is the same as the circumference of the medicine bottle A.

[0080] See also Fig. 9 As shown, the detection platform 1 is also provided with a light source system 7 for illuminating the industrial camera 4 during the irradiation process. The light source system 7 includes a light source conveyor belt 70, a driving member 73, and a detection column 71 arranged on the light source conveyor belt 70. The detection columns 71 arranged at equal intervals on the light source conveyor belt 70 are distributed in a one-to-one correspondence with the clamping blocks 21 on the clamping conveyor belt 20. A plurality of illuminators 72 are installed at equal intervals on the detection column 71. The driving member 73 is arranged on the light source conveyor belt 70 to control the movement of the light source conveyor belt 70.

[0081] When the industrial camera 4 performs defect detection on the product, in order to ensure the clarity of the detection, the present application also proposes a light source system 7, which is used to detect the product and ensure the clarity of the image captured by the industrial camera 4.

[0082] And the illuminators 72 are distributed in one-to-one correspondence with the clamping blocks 21. After the medicine bottle A is clamped on the clamping conveyor belt 20, the illuminators 72 are inserted into the medicine bottle A one by one through the light source conveyor belt 70 to ensure that the medicine bottle A is illuminated. At this time, when the industrial camera 4 performs defect detection on the product, its detection clarity can be effectively improved.

[0083] See also Fig.10 A method for detecting defects in drug bottles is shown as follows:

[0084] S1. Product processing: First, place the drug bottle A to be tested in a unified position, and start the equipment to test it to ensure the normal operation of the equipment.

[0085] S2. Product clamping: Start the conveying motor 26, which drives the clamping conveyor belt 20 to rotate through the conveying roller 23. Then the two clamping conveyor belts 20 rotate synchronously relative to each other. During the rotation of the two clamping conveyor belts 20, the clamping blocks 21 on the two clamping conveyor belts 20 approach each other, so that the drug bottle A to be tested can be clamped between the two clamping blocks 21 to limit the position of the drug bottle A. Then the clamping conveyor belt 20 continues to move, which can drive the drug bottle A to move along the length direction of the detection platform 1.

[0086] S3. Product inspection: The clamped product is conveyed, and surface defects are inspected after it moves to the specified position. After the drug bottle A is inspected for defects in the first inspection area, the clamping conveyor belt 20 continues to move, and controls the drug bottle A to move to the second inspection area. Subsequently, the industrial camera 4 in the second inspection area inspects defects thereon. Then, the clamping conveyor belt 20 continues to move, and controls the drug bottle A to be inspected for defects in the third inspection area and the fourth inspection area, respectively.

[0087] When the medicine bottle A enters the first inspection area, the industrial camera 4 takes a picture of it, and then analyzes the photographed picture to detect defects on its surface. However, it can only inspect one side of the medicine bottle A, and the medicine bottle A is a 360-degree three-dimensional structure. Therefore, the industrial camera 4 cannot capture multiple sides of the medicine bottle A in place.

[0088] S4. Product classification: When the inspected products meet the surface defect standards, they will be collected uniformly; products that fail the inspection will be discarded.

[0089] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
